Heart surgery is among the most complex forms of medical care, so choosing the right cardiac center can be an important part of treatment planning. The best heart surgery hospitals in the USA typically combine experienced cardiovascular surgeons, advanced diagnostic technology, specialized intensive care, minimally invasive treatment options, and multidisciplinary heart teams.
Patients may need cardiac surgery for coronary artery disease, damaged heart valves, aortic disease, congenital heart conditions, heart failure, or other serious cardiovascular problems. Modern cardiac centers can offer treatments ranging from coronary artery bypass grafting (CABG) and heart valve repair to robotic heart surgery, TAVR, ventricular assist devices, and heart transplantation.
This guide explains several major U.S. cardiac centers, common procedures, potential costs, and how health insurance may affect what a patient ultimately pays.

What Makes a Heart Surgery Hospital Stand Out?
A famous hospital name alone should not determine where a patient receives surgery. The right center depends heavily on the specific diagnosis and procedure required.
Important factors to compare include:
- Experience with the specific cardiac procedure
- Surgeon and hospital procedure volume
- Reported clinical outcomes
- Availability of minimally invasive or robotic surgery
- Dedicated cardiac intensive-care facilities
- Heart transplant and advanced heart-failure programs
- Cardiac rehabilitation services
- Insurance network participation
- Access to second opinions
- Experience treating complex or repeat surgeries
For complicated conditions, patients may benefit from centers where cardiologists, cardiovascular surgeons, imaging specialists, anesthesiologists and critical-care teams collaborate on treatment planning.
Leading Heart Surgery Hospitals in the USA
The following institutions are widely recognized cardiac centers. This is not a ranking, and the best choice for an individual patient depends on diagnosis, surgeon expertise, insurance coverage and other clinical factors.
Cleveland Clinic – Cleveland, Ohio
Cleveland Clinic has one of the world’s largest cardiovascular surgery programs.
Its Department of Thoracic and Cardiovascular Surgery treats coronary artery disease, heart valve disease, aortic aneurysms, arrhythmias, heart failure and other complex cardiovascular conditions. Cleveland Clinic reports performing 5,636 cardiac surgeries in 2023 and offers care for patients requiring repeat or particularly complex operations.
Major cardiac services include:
- Coronary artery bypass surgery
- Heart valve repair and replacement
- Robotic-assisted mitral valve repair
- Aortic and aortic valve surgery
- Minimally invasive cardiac surgery
- Maze procedures for atrial fibrillation
- Heart transplantation
- Ventricular assist devices
- Complex repeat heart surgery
Patients considering treatment should compare the experience and outcomes of the specific program relevant to their condition rather than relying solely on a hospital’s overall reputation.
Mayo Clinic – Rochester, Minnesota
Mayo Clinic provides cardiovascular surgery through major campuses in Minnesota, Arizona and Florida.
Mayo says its cardiovascular teams perform thousands of operations annually and treat complex cardiovascular and cardiothoracic conditions. Its program includes conventional open surgery as well as minimally invasive and robot-assisted techniques.
Available procedures include:
- Coronary artery bypass grafting
- Aortic valve repair and replacement
- Mitral valve repair and replacement
- TAVR
- Robotic heart surgery
- Aortic root surgery
- Congenital heart surgery
- Heart transplantation
- Ventricular assist devices
- Arrhythmia procedures
Mayo Clinic also notes that its Rochester, Jacksonville and Phoenix/Scottsdale campuses have received national recognition for cardiology and cardiovascular surgery.
Other Major U.S. Cardiac Centers
Patients researching advanced cardiovascular treatment may also encounter large academic programs such as NewYork-Presbyterian, NYU Langone Health, Mount Sinai, Cedars-Sinai, Stanford Health Care, Massachusetts General Hospital and Johns Hopkins Medicine.
Rather than assuming one center is universally superior, compare hospitals based on the exact procedure required. A center with extensive experience in complex aortic surgery, for example, may not be the same center a patient chooses for transplantation or robotic valve repair.
Common Heart Surgery Procedures in the USA
1. Coronary Artery Bypass Grafting (CABG)
CABG surgery, commonly called heart bypass surgery, is used to improve blood flow when coronary arteries are severely narrowed or blocked.
A surgeon creates an alternative route around the blocked artery using a blood vessel from another part of the body.
Depending on the case, patients may undergo traditional open-heart bypass surgery or another surgical approach.
2. Heart Valve Repair or Replacement
Heart valves regulate blood flow through the heart. When a valve becomes severely narrowed or begins leaking significantly, repair or replacement may be considered.
Treatment can involve the:
- Aortic valve
- Mitral valve
- Tricuspid valve
- Pulmonary valve
When appropriate, surgeons may prefer repairing a patient’s existing valve instead of replacing it.
3. Transcatheter Aortic Valve Replacement (TAVR)
TAVR allows doctors to replace a diseased aortic valve using a catheter-based approach rather than traditional open-heart valve replacement.
Whether TAVR or surgical valve replacement is appropriate depends on factors including the patient’s anatomy, age, valve condition and overall health.
4. Minimally Invasive and Robotic Heart Surgery
Some cardiac operations can be performed through smaller incisions instead of opening the chest through a traditional sternotomy.
Potential procedures include selected:
- Mitral valve repairs
- Valve replacements
- Cardiac tumor procedures
- Arrhythmia procedures
- Robotic-assisted cardiac operations
Cleveland Clinic explains that cardiac surgery can involve traditional open-heart operations or less-invasive methods, depending on the patient’s diagnosis and health.
5. Heart Transplant and Ventricular Assist Devices
Patients with advanced heart failure who have exhausted other treatment options may be evaluated for heart transplantation or a ventricular assist device (VAD).
These treatments are highly specialized and generally require evaluation at an advanced heart-failure or transplant center.
How Much Does Heart Surgery Cost in the USA?
There is no single price for heart surgery.
The total cost can vary substantially depending on:
- Procedure performed
- Hospital and geographic location
- Complexity of the condition
- Length of hospital stay
- Surgeon and anesthesia charges
- Diagnostic imaging and laboratory tests
- Medical devices or implants
- ICU care
- Complications
- Rehabilitation
- Insurance network status
It is also important to distinguish between a hospital’s charges, negotiated insurer rates, Medicare payments and the amount a patient actually owes.
For example, CMS data for one U.S. heart hospital show that average covered charges for certain coronary bypass categories can exceed $160,000 or $270,000, while average Medicare payments for those categories are substantially lower. This illustrates why a hospital’s listed charge should not be interpreted as the patient’s expected bill.
Patients should therefore request an individualized estimate from both the hospital and their insurer before a scheduled procedure whenever possible.
Does Health Insurance Cover Heart Surgery?
Many medically necessary cardiac procedures can be covered by private health insurance, employer-sponsored insurance, Medicare or Medicaid, subject to the terms of the patient’s plan.
However, coverage does not necessarily mean the patient pays nothing.
Potential patient costs can include:
- Deductibles
- Copayments
- Coinsurance
- Out-of-network charges
- Non-covered services
- Prescription costs
- Rehabilitation expenses
Before scheduling non-emergency surgery, patients should verify whether the hospital, cardiac surgeon, anesthesiology team and other involved providers participate in their insurance network.
Prior authorization may also be required.
For example, Mayo Clinic says it works with hundreds of insurance companies, but notes that insurer referral and other requirements can vary.
Medicare Coverage for Heart Surgery
Medicare can cover medically necessary cardiovascular care when eligibility and coverage requirements are satisfied.
For 2026, the Medicare Part A inpatient hospital deductible is $1,736 per benefit period. Part A generally covers eligible inpatient hospital services, while other portions of Medicare can apply to physician and outpatient services.
Actual out-of-pocket expenses vary according to the treatment, length of stay, supplemental coverage, Medicare Advantage enrollment and other circumstances.
Patients should confirm current benefits directly through Medicare or their plan before elective treatment.
How to Compare Cardiac Centers Before Surgery
For planned surgery, consider asking the hospital or surgeon:
- How many times does this team perform my specific procedure each year?
- What outcomes does the program report for patients similar to me?
- Is minimally invasive or robotic surgery appropriate in my case?
- What are the major risks and alternatives?
- Is the hospital in my insurance network?
- Is the surgeon in-network?
- Does my insurer require prior authorization?
- What is the estimated patient responsibility?
- How long is the expected hospital stay?
- What follow-up care or cardiac rehabilitation will I need?
For a particularly complex diagnosis, obtaining a second cardiac opinion can also help patients understand available treatment approaches.
Heart Surgery Recovery and Rehabilitation
Recovery depends on the type of surgery and the patient’s overall health.
Traditional open-heart surgery generally requires more recovery time than many catheter-based or minimally invasive procedures. Patients may initially need restrictions involving driving, lifting and strenuous activity.
A structured cardiac rehabilitation program may include monitored exercise, cardiovascular education, nutrition guidance and risk-factor management.
Patients should follow the individualized discharge and rehabilitation instructions provided by their medical team.
Frequently Asked Questions
What are some major heart surgery hospitals in the USA?
Major U.S. cardiac programs include Cleveland Clinic, Mayo Clinic and several large academic medical centers. The appropriate hospital depends on the patient’s condition, required procedure, surgeon expertise, outcomes and insurance network.
How much does open-heart surgery cost in the USA?
There is no universal price. Hospital charges can reach well into six figures for major cardiac operations, but negotiated insurance rates and Medicare payments can be substantially different. The patient’s actual responsibility depends heavily on insurance and the specific treatment.
Does insurance cover bypass surgery?
Medically necessary CABG is commonly covered under major health insurance programs, subject to plan rules such as deductibles, coinsurance, network requirements and prior authorization.
Is robotic heart surgery better than open-heart surgery?
Not necessarily. Minimally invasive or robotic surgery can offer advantages for selected patients, but it is not appropriate for every heart condition. A cardiovascular surgeon should determine the most suitable approach.
What is the difference between CABG and TAVR?
CABG treats blocked coronary arteries by creating new pathways for blood flow. TAVR treats a diseased aortic valve by replacing it using a catheter-based technique. They address different cardiovascular problems.
Final Thoughts
Choosing among the best heart surgery hospitals in the USA should involve more than comparing famous hospital names. Patients should focus on the center’s experience with their specific condition, surgeon expertise, outcomes, available technology, insurance participation and expected out-of-pocket costs.
Leading cardiac centers offer treatments ranging from CABG and heart valve surgery to TAVR, robotic cardiac surgery, heart transplantation and advanced heart-failure care.
Before undergoing elective heart surgery, patients should discuss treatment options with a qualified cardiologist or cardiac surgeon and confirm coverage, prior authorization and estimated costs with their health insurance provider.
